.SH SYNOPSIS
.sp
ibqueryerrors [options]
.SH DESCRIPTION
.sp
The default behavior is to report the port error counters which exceed a
threshold for each port in the fabric.  The default threshold is zero (0).
Error fields can also be suppressed entirely.
.sp
In addition to reporting errors on every port.  ibqueryerrors can report the
port transmit and receive data as well as report full link information to the
remote port if available.
.SH OPTIONS
.sp
\fB\-s, \-\-suppress <err1,err2,...>\fP
Suppress the errors listed in the comma separated list provided.
.sp
\fB\-c, \-\-suppress\-common\fP
Suppress some of the common "side effect" counters.  These counters usually do
not indicate an error condition and can be usually be safely ignored.
.sp
\fB\-r, \-\-report\-port\fP
Report the port information.  This includes LID, port, external port (if
applicable), link speed setting, remote GUID, remote port, remote external port
(if applicable), and remote node description information.
.sp
\fB\-\-data\fP
Include the optional transmit and receive data counters.
.sp
\fB\-\-threshold\-file <filename>\fP
Specify an alternate threshold file.  The default is /etc/infiniband-diags/error_thresholds
.sp
\fB\-\-switch\fP  print data for switch\(aqs only
.sp
\fB\-\-ca\fP  print data for CA\(aqs only
.sp
\fB\-\-skip\-sl\fP  Use the default sl for queries. This is not recommended when
using a QoS aware routing engine as it can cause a credit deadlock.
.sp
\fB\-\-router\fP  print data for routers only
.sp
\fB\-\-clear\-errors \-k\fP Clear error counters after read.
.sp
\fB\-\-clear\-counts \-K\fP Clear data counters after read.
.sp
\fBCAUTION\fP clearing data or error counters will occur regardless of if they
are printed or not.  See \fB\-\-counters\fP and \fB\-\-data\fP for details on
controling which counters are printed.
.sp
\fB\-\-details\fP include receive error and transmit discard details
.sp
\fB\-\-counters\fP print data counters only
.SS Partial Scan flags
.sp
The node to start a partial scan can be specified with the following addresses.
.\" Define the common option -G
.
.sp
\fB\-\-port\-guid, \-G <port_guid>\fP  Specify a port_guid
.\" Define the common option -D for Directed routes
.
.sp
\fB\-D, \-\-Direct <dr_path>\fP     The address specified is a directed route
.INDENT 0.0
.INDENT 3.5
.sp

.ft C
Examples:
   \-D "0"          # self port
   \-D "0,1,2,1,4"  # out via port 1, then 2, ...

   (Note the second number in the path specified must match the port being
   used.  This can be specified using the port selection flag \(aq\-P\(aq or the
   port found through the automatic selection process.)

\fBNote:\fP For switches results are printed for all ports not just switch port 0.
.sp
\fB\-S <port_guid>\fP same as "\-G". (provided only for backward compatibility)
.SS Cache File flags
.\" Define the common option load-cache
.
.sp
\fB\-\-load\-cache <filename>\fP
Load and use the cached ibnetdiscover data stored in the specified
filename.  May be useful for outputting and learning about other
fabrics or a previous state of a fabric.
.SS Port Selection flags
.\" Define the common option -C
.
.sp
\fB\-C, \-\-Ca <ca_name>\fP    use the specified ca_name.
.\" Define the common option -P
.
.sp
\fB\-P, \-\-Port <ca_port>\fP    use the specified ca_port.
.\" Explanation of local port selection
.
.SS Local port Selection
.sp
Multiple port/Multiple CA support: when no IB device or port is specified
(see the "local umad parameters" below), the libibumad library
selects the port to use by the following criteria:
.INDENT 0.0
.INDENT 3.5
.INDENT 0.0
.IP 1. 3
the first port that is ACTIVE.
.IP 2. 3
if not found, the first port that is UP (physical link up).
.UNINDENT
.sp
If a port and/or CA name is specified, the libibumad library attempts
to fulfill the user request, and will fail if it is not possible.
.sp
For example:
.INDENT 0.0
.INDENT 3.5
.sp
.nf
.ft C
ibaddr                 # use the first port (criteria #1 above)
ibaddr \-C mthca1       # pick the best port from "mthca1" only.
ibaddr \-P 2            # use the second (active/up) port from the first available IB device.
ibaddr \-C mthca0 \-P 2  # use the specified port only.
